In the first wave of nonunion hiring, Mayor Martin J. Walsh turns to familiar faces

Mayor Martin J. Walsh has repeatedly vowed to build an administration that reflects the diversity of Boston, a city in which people of color and women make up more than half the population.

But a Globe analysis of city payroll records found that the Walsh administration’s first wave of new hires, which includes both Cabinet chiefs and junior aides, was overwhelmingly white and predominantly male.

More than half of the 39 nonunion employees brought into the administration during the mayor’s first month in office live in Walsh’s political power base in Dorchester and South Boston, and almost all came from the ranks of Walsh’s campaign.

In an interview this week, Walsh strongly rejected any suggestion that he had fallen short on his commitment to diversity.
